T0 a/ZZ whom, t nfl/Cty concern,.-

Be it known that I, GOTTFRID ERIcsoN, a citizen 0f the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New York, have invented a new and ImprovedButter-Cutter, of which the following is a full, clear, and exactdescription.

The invention relates to a butter-cutter -of that class in which cuttingedges are provided to be forced into the tub or mass of butter, thusforming a cake which is subsequently separated from the body of thebutter by a cutting-wire or the like, the device being then withdrawnwith the cake of butter thereon and being provided with anejectingplunger by means of which the cake may be delivered.

The object of my invention is to simplify the devices of this sortheretofore produced, so as to enable the desired end to be attained atless expense. I attain this obj ect by certain special features ofconstruction and relative arrangement of parts, all of which will befully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, which illustrate asan example the preferred embodiment of my invention.

In the drawings, Figure 1 is a vertical section of the invention. Fig. 2is an elevational view with parts in section on the line 2 2 of Fig. 1.Fig. 3 is a detail elevation showing the preferred means for guiding thecuttingarms. Fig. 4 is a detail view of a modified form of thesedevices. Fig. 5 is a section on the line 5 5 of Fig. 4.

The device is provided with two oppositelydisposed cutter-plates 10,which are preferably formed of an integral section of metal connected bya web 11 which is located at the outer or upper ends of thecutting-plates and extend across between them. Fastened to saidconnecting-web 11 is a plate 12, which has at each-endoutwardly-extending brackets or standards 14, which are provided witharc-shaped upper edges 14a7 terminating in.

shoulders 14h, and at the inner sides of the plates these edges areprovided with beads 14, curved in conformity to the edges 14a. Securedin each bracket or standard 14 is a headed stud, or screw 15, formingthe pivots of the side cutting-arms 16. These arms are provided, asindicated by the broken lines in Fig. 1, with slots 17, in which saidstuds 15 are received. The arms are also provided withI hooks 18, whichare securedv to the arms andv loosely embrace the respective beadsL 14.

Consequently the guiding-arms 16 wheny swinging on the pivot-studs 15are forced also to slide thereon, the slots 17 permitting,

arms 16 are tapered, as shown inFig. 1, and

when in position at one side of the device their outer edges extendvertically true withf the side edges of the adjacent cutting-plate 10.

When the cutting-arms reverse their'position their opposite edges extendvertically true with the side edges of the opposite cutting-plate 10.Said arms 16 perform, therefore, the double function of cutting thebutter away between the side edges of the plates 10 and also of formingtwo sides walls of theinclosure or box in which the print orblock-ofbutter is held when it is withdrawn from the remaining mass of butter.The arms 16 carry the usual cutting-wire l 8 which extends acrossbetween the pointed inner ends of the arms,

as shown, and up alongside eachvarm, the ends of the wire being woundover pins 19,v

which are rotatable in the arms and provided with worm-wheels 20,engaging arms 2l` 'onf thumb-pins 22, which pins are revoluble lin thelrespective arms. By this means the tension of the wire 18 may beregulated at will'. The

inner surfaces Vof the plates 10 are formed with grooves 23, whichreceive the -wire '18, so as to permit the parts 10 and 16 to be enteredinto the mass of butter without interference on the part of the wire.After this has ybeen done-it is only necessary to swing the arm 16across from one to the other side of the device, -thusl not only cuttingaway the butter at the sides between the edges of the plates 10, butalso cutting away the butter at the inner ends of the said plates, thuscompletely separating the block of butter from the remainingvmass.`

The arms 16 have inwardly-curved extensions 16, which meet each other ata handle 24, and by means of which handle the arms 1 6` may be operated,as explained. Y Fastened on'the plate 12 is the base 25 of-ra tubularstanchion 26. This stanchion loosely receives a plunger-rod 27, and thestanchion has a longitudinal slot 2611, through which extends the tangof a handle 28, fastened to IOO IIO

lwhich operates through the walls of the tubular,l standard 26 and is inconnection with said plunger-rod. lnclosed in the enlarged portion ofthe tubular stanchion 26 is a helical spring 29, which bears on theplate 12 and against the handle 28 when the rod 27 is pushed down, thisspring tending to return the rod to the raised position shown in Fig. 1.The lower end of the rod 27 projects through the plates 12 and 11 andcarries a plungerblock 30, which slides between the side plates 10 andcutting-arms 16 and is intended to eject the block or print of butterafter same has been severed from the mass. The upper portion of the lot261is provided with a scale or graduation 3]., and coacting therewith isa pointer 32, carried on a threaded sleeve or nut 33. This sleeve or nutis loosely contained within the upper part of the tubular standard 26,and acting within the same is a screw 34. The screw is held in the upperextremity of the standard 26 to rotate by means of set-screws 35operating in an annular groove 36 in a head 37 of the screw. 4Said headprojects outside of the standard and is knurled to permit easy manualoperation of the screw. At its upper extremity the stanchion 26 carriesa transversely-disposed handle 38; (Best showninFig-2.) Byrotatingthescrew 34 the nut 33 may be moved up or down in the stanchion 26, andthis nut lying in the path of the plunger-rod 27 will limit the upwardmovement thereof. Consequently by means of this device the position ofthe plunger-block 3() may be regulated at will, thus regulating the sizeofthe block or print of butter separated from the remaining mass. 39indicates a' stop-pin,

a thumb-lever 40, by means of which the stoppin may be moved inwardafter the descent of the plunger-rod 27, so that the stop-pin will limitor prevent the return movement of the plunger. This constitutes anothermeans for limiting the inward movement of the block 30, and this seconddevice is useful in the event should it be desired to greatly reduce theamount or weight of the butter separated. For instance, if the cutter issupposed to have one pound capacity by operating the stop 39 thecapacity may be reduced to one-half pound or to one-quarter pound.

Figs. 4 and 5 illustrate a modification of the means for imparting asliding movement to the side cutting-arms 16. This modification consistsin an arc-shaped slot 14d, taking the place of the bead 14C.I Throughthese slots eyebolts 41 extend, and the eyebolts carry pins 42, on whichrollers 43 are arranged. These rollers run against the sides of thebrackets 14, while the eyebolts running in' the arc-shaped slots 14dcause the side cutting-armste take a sliding movement at the same timethat they swing around the pivot-studs 15.

In the useof the invention the nut 33 or the stop-pin 39, if desired,should be adjusted so as to place the ejector-block 30 in the properposition. This block serves, it will be observed, the twofold functionof ejecting the print or block of butter and of adjusting or controllingthe size of said print. After the block has been adjusted to the desiredposition the side plates 10 and cutting-arms 1.6 should be forced intothe mass of butter from which the block or print is to be taken untilthe butt-er meets the block. Then the handle 24 should be operated so asto cause the side cutting-arms 16 to swing across from one plate 10 tothe other, these plates thus keeping the butter at the sides andcarrying the wire 18 across between the ends of the plates 10, so as tocut off the butter at the inner end of the print or block. The deviceshould then be withdrawn from the butter, the block or print being heldbetween the side cutting-arms 16 and the plates 10, and the operation isended by forcing out the plunger-block 30, thus ejecting the print.

Having thus described the preferred form of my invention, what I claimas new, and desire to secure by Letters Patent, is-
